[Q] My phone won't connect on USB to computer, but my wifes Epic will

I have a Samsung Epic 4g rooted with the one click 2.5 and I upgraded to Froyo.
I had to use my wifes phone to copy the update.zip to my sd card because my computer would not let me see my epic. Same computer, cable and model phone works fine for my wifes.
I need to reinstall the one click root and can not get my computer to see my phone.
Is there a way I can root on the phone without using the computer.
So close to done, but I can not use the wifi tether without re-root

Different phones can be more finicky. No valid explanation why though.
Make sure you plug the cable into the phone first, then the computer. Try using different USB ports. If all else fails, try another cable.
I have seen a bad port on the phone before, but it had charging issues as well.

I have tried all the ports on my laptop. The phone acts like it is connecting. Even brings up the new usb connection icon but can not see the phone or sd card on my phone. USb debugging tried on and off.
No problem charging. I have tried various usb cables also and different computers

That is pretty wierd.
Do you have a different computer to check?

I'm having the same issue, but it isn't constant. I spent hours last night reinstalling drivers, different cables, debugging on-off. I go back to stock and try and it works fine, I install clockwork3 and ext4 with TrulyEpic and it does the same thing. Though sometimes it works. I found that my port is a little loose, cause when I move it to one side it looses connection. I think we may need to contact Sprint and get a replacement phone. I really want a brand new one, cause I didn't pay for a refurb, and really dont want one.

Sounds like something is up with the phone, man. The only commonality is the phone.
Especially if you couldn't access it before the flash to 2.2 either.

duh. It's already been scientifically* proven that phones perform better for women because they are often carried (snuggled) in the women's bra. See here...

I find my USB very finnicky on my phone connecting to my windows 7 computer,I've gotten used to just using File Expert to wirelessly manage my SD card.

Anyone get it to sync with their mac

I downloaded the android mac tool and it still doesn't read my tab 10.1. It reads and connects my xoom but not the galaxy tab.

Not compatible with Mac (yet? ever?). I've actually had to go dig an old XP HDD out of storage so that I can adb and transfer files back and forth.

that sux balzzz

No luck for me either...
Doesn't work for me either. After doing the 3.1 update for my LE Tab tonight I tried the Android File Transfer program with "usb debugging" both enabled and disabled but with no luck either way. I even tried re-downloading the Android File Transfer app from Google but it's the same version that's been up there since April.
Any Mac folks have a workaround besides using the painfully slow ddms debugger interface or doing network-based transfers (like smb or ftp)?

I think you need to use this. I haven't tried it yet though.

we did doesnt work thanks

Hasn't worked for me either. I'm assuming that Android should the update to the app ready by next week for the Tab's wide release but that's wishful thinking. What about the Xoom and Transformer owners who also got the 3.1 update.:-\

Wait is this for real... A friend of mine and I just got ousr at the NY event, but a friend has to ship them to us. Will it not work with Macs? My friend has a Mac book... This would be terrible news...

At the moment, no it does not sync with Macs. Th Android File Transfer app hasn't been updated yet with the proper "drivers" to sync with Mac, but it should get updated soon. This isn't a "forever" type deal

I picked mine up yesterday, no syncing. Kies doesn't even recognize the device yet. Works with windows 7 though.
Interestingly, Adobe Lightroom is able to find the tab on my macbook.

I would just keep checking here:
http://www.samsung.com/us/support/downloads/GT-P7510MAVXAB
They had a Mac version that I downloaded before they took it down and it works. Not sure exactly why they took it down. Sorry I didn't save the dmg file.

i'm on the same boat, my xoom was working fine with SL, but my SGT doesn't work

I have been using FTP (SwiFTP on the marketplace) to transfer files until samsung or google get this fixed. I find this to be a ridiculous problem to be having.

Also, I tried Samsung Kies BETA for Mac and no dice.

@NoLeftTurns You're welcome! Glad your enjoying it! Kies for Mac will be here soon, we'll keep you posted! =) ^Sabrina

I'd prefer Kies-less entry honestly. (sorry for the pun...i had too ) I've been using ES File Explorer to connect to my NAS device and grabbing files from there. Far from ideal, but it could be worst

I just downloaded the latest version of kies and it seems to be working fine on my 2011 macbook pro... anyone know why the GT won't charge when it is plugged in, tho? i just have a red X over the battery...

I think i read somewhere what the SGT cant charge it with the usb cable connected to a computer port, my SGT indicate the same X with my MBP.
The kies app with the least samsung drivers works fine, but is bad i cant mount the sdcard like a hd storage.

Because the Tab requires more power than your USB port can provide.

Am I Missing Something? WTF? How Do I Connect to a Computer?

Love the device. Great build, feels nice - just like everyone else says.
Why would anyone release a device that can't connect to a computer to transfer files? Am I missing something? I've tried connecting on Mac and Windows and searched high and low for drivers, tips, tricks, etc. Don't tell me Dropbox or some other back door solution. The whole reason I bought Android (I already have 2 ipads) is to eliminate itunes. Why would I want to have to use a software solution to transfer files - I would just stay with itunes if that were the case. I have an EVO 4G that mounts as a hard drive and when I load files the app recognizes (photo, music, video) and plays it. WTF!!!!!!
Can someone help? NO I AM NOT INTERESTED IN SOME STUPID WORKAROUND spending 30 hours at the risk of bricking and voiding warranty ending up with some laggy piece of crap custom ROM just to do ONE SIMPLE TASK - DRAG AND DROP! No offense, I respect what you hard cores do. I don't have time. I need $500 devices to work as expected.
Oh yeah, stupid POS wouldn't play an AVI file either. No idea why. Don't really care. It took 2 hours to transfer a file via Dropbox. Not doing that again.
Suggestions welcome. My Samsung Tab 10.1 is currently for sale on ebay. Maybe I'll take it down if some kind soul out there can help me figure this out.

Had the same issue. You just need the correct drivers for your PC. Hope that helps.

Try installing this on your mac - Android File Transfer
For some reason, Honeycomb devices don't mount as regular mass storage device, but rather under the Microsoft MTP protocol (verified when my friend with a mac told me I needed to install the Anrdoid File Transfer when I connected his Xoom to my Win7 laptop. I told him he's crazy, but he didn't know since he never connected his Xoom to a PC running Windows).
Hopefully it's fixed for the retail 10.1 tabs.

If you disable "USB debugging," your PC should recognize it as external storage.

I seem to have having the same problem (10.1).
I installed the samsung mobile drivers, and disable usb debugging.
Now when i plug in my tablet it says connected to samsung kies. On windows i get the pop-up for a usb storage connection, but I cant actually view the files and this doesn't show up in my computer.
Do i have to install samsung kies? I only installed the mobile drivers 'Samsung_USB_Driver_P4_Including_Escape'
Any help?

I installed both. My windows 7 identifies it with a mobile phone icon, but under it the sdcard is identified as a tablet(default name). When i connect it to my pc my GT displays "connected / press home key to quit Samsung kie" so I guess kids is requisite.

Thanks for the help. Installed Android File Transfer but still no luck with debugging on or off. It just says "No Android Device Found"
Maybe I have a bad unit or something?
Are there any Mac users out there that have been able to connect? I also have a Vista PC that I will start toying around with.

Use file manager app and do it wirelessly via wifi
It is easy and you dont need a pc ...

I've been having the same problem. It seems that the Android File Transfer program hasn't been updated since the change to 3.1. I'm pretty confident that it'll be fixed shortly. However this is an Android issue not a Samsung issue- . The Xooms and Transformers are having the same problem.

I'm leaning towards that it's a Samsung issue as my friend has both a Xoom and Transformer on 3.1 and Android File Transfer is working fine for them.

I've the 10.1v and I just plugged the usb cable and I saw the device as an external storage. Probably the problem is limited to the I/O devices.
For Divx try downloading "MoboPlayer". I thnink that the default avi player can play only h.264 files

Uhh from when i got my tab i had this problem as well all i did was go into control panel uninstall the drivers installed from the first time of plugging it in .. Then i went onto the tab disabled debugging and connected again let it install its drivers and i was set to go just make sure u have samsung kies installed onto your computer so it can find drivers and once the drivers were installed i went into my computer and it was there named something like pt-901 something lol hopefully this helps..

Thanks for this. Works great. Getting better...
I still don't know how any OEMs are going to gain traction against Apple among the masses who don't have the patience to figure this stuff out. Luckily I have some time on my hands this weekend!
Dropbox is taking about 30 minutes to transfer a 700MB file from my laptop to my box and then DL to the Tab's memory. Not a great solution. Need to figure out this USB file transfer thing.

What codec was used for your AVI file? Xvid? If so, then that's whack of Samsung to list Xvid and AVI as native support under their specifications.

Do you need to install the Samsung Kies onto every computer you want to transfer files via USB with?
Other Android devices I haven't had to install any third party software for this.

Same here. Every other Android device I've had is drag and drop on both Mac and PC which is the main draw for me. EVO, Archos, etc, etc...
I also thought that Samsung claimed native playback for Xvid AVI files...??? Apparently not.

Finally works!!! While I was messing around with drivers for PC I discovered that Samsung posted and updated (June 9th) version of Kies which allows easy files transfer on Mac. Problem solved.
Now I just need to figure out how to charge over USB so I don't have to lug this brick of an AC adapter around and I'm converted!

The above is where I was able to DL both PC drivers and Kies for Mac that WORKS! One thing to note - make sure that you are on the Samsung US site. Originally I was on Samsung.com/ca domain and none of the files would work. When I switched to the US site at Samsung.com (scroll to the bottom to change location) the files worked.

Plz! See this thread! USB LOOSE CONNECTION!

OK! I have got 2 pcs win 7 and win XP! I have an ANDROID PHONE!
I have an XPERIA X10i.
This thread is important because many haven't noticed this problem or even bothered,I am about to share! many people with xperia x10i and other android phones face this problem!
THIS PROBLEM IS ABOUT LOOSE CONNECTION between Android phones and windows 7 pc!
WHY the **** I AM HAVING USB LOOSE CONNECTION?????????????????????????????????????????????????????????????????????
My phone has android 2.1 rom which i sony's original one!
I have rooted the phone now!
(I had changed roms many time android 2.2,2.3.....)
It seems that there is a bit incompatibility between android OS and windows 7!
The problem is that the usb drivers of android 2.1 and 2.2 is incompatible with windows 7!
When ever i connect my x10i with my pc by usb the connection goes loosen!
repeatedly notification shows Mount and unmount! Which is very annoying! VER.......VERY......ANNOYING!
I tried many stuff..I searched google.....windows forums..coustomer supports....! But I assure u people this is windows 7's problem!
sometimes my usb get connected but chance is 2% out of100%!
I herd there is a problem with SEMC_HSUSB(Sony Ericsson sa0101)
but android 2.1 worked fine for me on windows 7!
whereas my windows xp works fine with my x10!
I checked if my windows 7 has any problem in usb ports or software setting,but turned out to be just fine!
I searched google,in google some said x10i,galxy S,moto Droid also had loose connection in usb connection!
even my usb plug is fine!
there are few win7 which makes android run smoothly and some don't!
Well I am the one with not working one!
Can anyone help me out here!
is this a Kernel problem?
my windows xp and wndows 7 are genuine(original version) and also they r fully updated!
I need help!

have you ever thought it maybe a problem with something else??
i have connected my x10 with 1.6, 2.1 and about 4 different custom ROMS (again 2.1 or 2.2)...all connect perfect with all my pc's and laptops running win 7 ultimate (64bit) and win xp
try a different usb port / computer / cable
Also check your usb on the phone...it maybe loose
Have you tried it on a win xp machine??

I tried different ports but its problem with the software of kernel or any reason that i don't kno!

there could be a number of reasons...technology is wonderful when working....but a pain when its not!!
sounds like something might be conflicting but not showing as a conflict
If you plug other things in the same computer ports and they work ok then all i can suggest (and its drastic) is to reinstall windows and start fresh. That will get rid of any old corrupt files and software and you will probably find it will work.
I have never found anyone stating a problem with SE and windows

Have you ever though that you might have a faulty phone? Just call your carrier or se to see what they can do for you its an hardware issue. Lets hope all this will get sorted out for.you

I checked the phone! but turned out to be fine!
I tested on my friend's win7 which made it work smoothly!
THERE IS NO HARDWARE ISSUE! THIS IS SURE TO BE A SOFTWARE STUFF!

Worked on friends win 7 which it worked
which boils down to the problem being on your pc
You can spend hours and hours trying to find the conflict or the problem why its not working or as said previously, format the pc, reinstall a fresh version of windows and should be ok (providing the USB ports on your pc work ok)

LOL! I have a 7TB HDD LOL!
LOL IF U TELL ME TO REINSTALL MY PC THAT WOULD BE EPIC ****!
can anyone give me a driver! lol any help out there?
LOL!

I have the same issue with my work computer but not my home computer. Not sure what the reason is but it's definitely annoying. Work computer has Vista, my home computer runs 7. I have two X10's and my work computer has never liked either one. For some reason it only happens when I am running the SE's 2.1.
Definitely sucks. I would attribute it to 2.1 and some computers. Luckily once connected to flash tool all is good and it doesn't disconnect while flashing.

its not as simple as giving you a driver...you need to find why its not working. When you plub in the usb it should install the driver.
If you dont wanna format then all i can suggest is uninstall the sony driver and hope when you install it next time it works
failing that i think you have 2 possibilities....
1> Hope that the 7tb hdd is partitioned!!
or
2> Stay good mates with your friend!!
Thats all i can suggest
Good luck...think you will need it!!

PLZ ANYONE HELP!but why does this software conflict happens!
Well I ran the troubleshooter(windows device compability) and it showed a problem of compatibility!
This usb is so sensitive if i even move the mobile 1 mm it will disconnect or just popup "MOUNT PHONE" AND "UNMOUNT PHONE" This is very much annoying!
well this ain't hardware problem but then why loose connection????
It is surely software problem but is it possible that software can make USB ports superduper sensetive???????
LOL! I can reinstall phone but I tried but not working!
I can also reinstall WIN 7 but lol I can't its a huge weight lol! LOL I have 7TB HDD and lol I have many thing in it!so i can't jsut reinstall!
So can anyone give me sony xperia x10i usb driver????THIS IS BLOODY SOFTWARE BUG!!!!
Though 1 weird thing I forgot to mention! The Weird thing is that FLASH TOOL,sony ericssion update, root kit tool and etc rooting software works and don't show any loose connection!
So I checked my SD CARD but SD card is fine! So....wat is it? Is it USB PORT SPEED stuff or software conflict??
but this problem is mainly seen in win7 so i guess win7 hates android! But why would people suddenly face this problem!
Yes before 1 month everything worked fine!but for this month my days r ****ed up!
I think the KERNEL OF ANDROID or WIN7's usb drive for android phones have some bugs!
well problem needs to be dected then lol we can find cure!
(I copy files from PC to my mobile very luckyly lol! sometims try to reconnect it 30 times repeatedly works though if I move the phone a bit it just get disconnected!
OK! so how about we get c\windows\system32\winusb.sys from win xp and put it iin win 7! lol I don't know wat could happen lol! but its a try but its lol risky!
this is usb setting for xp lol! but I don't kno if win7 and xp has same versio of USB dlls!

It's definitely not Windows 7 that's giving it issues. Sorry to say but it's the computer. I'm not sure why it happens but it happens to my work computer running Vista but not my windows 7 home laptop. Don't know if there is a fix though. But as long as flash tool works who cares right? Mounting works fine when you mount it right? It's just the beginning issue when it disconnects, but once connected you should be good.

Hey do u have PC companion installed? And check to see you have USB debugging enabled. My phone did the same thing. I fixed it by enabling USB debug

Phone cannot be seen by any PC

My phone is a huge POS and I am ready to throw it through t-mobile's window. I have been getting a lot of hangs and crashes on my phone so I decided it was time to finally upgrade it. Well I have tried both my work and home PC's and my laptop. And the phone never shows up on the computer. When I plug it in, the phone beeps and asks me if I want to use Kies, Mass Storage, or Media Player. No matter what I select the phone is never seen by windows explorer, disk manager, or Kies. I have tried a few different cables and still no dice. I know the connection is good as it charges and asks if I want to mount the device. I figured it was software so I decided to factory wipe the phone, but that didn't help at all. I am at a loss, T-Mobile probably won't do anything for me. I am ready to jump ship and go back to iPhone, Android has not been a very good experience for me.

Ye sorry you had to get the vibrant dude. I would have gone with the nexus s on tmobile. Maybe try to enable USB debug. I don't know for a fact if it might help. Otherwise if you're willing to deal with it and put in a little time you could root it and run bionic 1.3.1 and just do the basics with it. With rooting you can go much farther but I dont think you care for much more than the basics. This phone is a great hardware unfortunately the software is not upto par. This isn't so much android as it is Samsung for crippling it with their touchwiz overlay and rfs format.

First, download your phone usb driver from Samsung and install on your PC or laptop.
Try these steps:
1. Click the menu
2. Click Setting
3. Click Wireless and Network
4. Unplug USB
5. Click USB Setting
6. Select the last option
Good luck

I know what you are going through. I have had to uninstall and reinstall the drivers so many times.
If you are able to get the phone updated to Froyo it will be much better. If you are willing to get your hands a little dirty, look into installing the famous Voodoo lagfix. It makes a night and day difference!

if you wanna update to froyo 2.2 i would suggest using kies mini

Going to bump this. Phone still is not recognized by any PC. It's not a driver issue. It charges, but does not allow me to transfer files or anything.

I have the two vibrant and one with your problem. The one with the problem was bought used and I'm sure that the seller had no intention of ripping me off because the from was the factory stock . Anyways it doesn't open as a mass storage or is detected in Odin. The best thing I could do was flash cyanogen or miui on it and that's how I keep up to date. I believe that this Is a hardware problem. Perhaps by water, dust, or who knows what. Nothing I can do about it.

If you had a Linux box to plug it into, you could probably find out more of what is going on. You could try putting the phone into download mode and see if Odin can see it. It could well be a bad USB port. You could take it into T-Mobile and ask them to try.
It's not an android problem, but it could be cheap Samsung hardware or bad software.

All three comps using the same os?
Same driver version for all three?
Is it recognized in device manager when plugged in?
If all you need to do is transfer files, then use Samba

I have had this problem before, make sure the USB cable your using is a data usb cable, and not just a charge cable, yes they do exist.

Look this might sound stupid, but try different cables, even a new one if possible, and ask them to test it for you. I had the same problem and I had a working cable (or so I thought), one day a friend lend me his cable so I tried once more, expecting the usual, but it was recognized by my pc. It was a bad cable all along.

I had the same problem and I had a working cable (or so I thought), one day a friend lend me his cable so I tried once more, expecting the usual, but it was recognized by my pc. It was a bad cable all along.

This is possible, I was using a Generic cable and could not get Odin to recognize it until I used the official Sony cable at one time a few months ago.
